Union City, Ind. - A proposal to build a pet food flavoring plant in eastern Indiana is raising a stink among residents.

Nebraska-based Naturally Recycled Proteins wants to build a $10 million plant on 20 acres about two miles outside Union City. The plant would use a slurry made from grinding up old laying hens to make a protein and flavor additive for dog foods.

Company officials acknowledge there's a potential for odor but say golf course owners within 6.5 miles of its Iowa plant have never received complaints from customers.
